and consists of improvements in the startingand stopping-mechanismtherefor. IMy improvements are directed partlcularly to that type ofmachine known as frictiondrive or drum-winders in which the cop orpackage is rotated through fictional contact of its surface with adriving-roll or drum, The object of the invention is to provide aquick-acting, positively-operated means for removing the cop fromdriving contact with thedr-ive-roll, and for releasing the yarn from thetraversing thread guide when it is desired to stop the winding. Otherobjects of the improvement are to provide means for controlling themovement of the winding-spindle o-r mandrel as it recedes from thedrive-roll during the growth-of the package; to apply a braking force tothe mandrel to insure quick a restmen't of its rotation; to hold themandrel in its raised position upon the stopping I of the machine; andto otherwise facilitate and render more convenient the whole operationof the machine.

The manner and means for carrying out the improvements are fullyexplained in the following specification, illustrated by theaccompanying drawings, in which like reference characters designate likeparts. In .the drawings Figure 1 is a general, plan View of my improvedwinding machine;

My improvements are herein shown as applied to a machine of the samegeneral construction as that described and illustrated in my copendingapplication, Serial NO. 105,425, filed June 23, 1916. Referringparticularly to Figs. 1 and 2, the essential elements of thewinding-mechanism are mounted on a box-like casing or frame F andcomprise the winding1nandrel B, the driveroll D, the thread-guide Gr andthe traversecam C. Journaled in bearings at the sides of the frame F isa horizontal shaft S on which the cam G is fixedly mounted and at oneend whereof is a friction drive-wheel W. Mounted in a movable bracket orstandard E at the rear of the machine is a stud shaft h, carrying abelt-pulley H at one end, and at its opposite end is a friction-disk Karranged with its face engaging the periphery of the cam-driving wheelW. The pulley H is connected by a belt to the main drive-shaft of themachine, usually arranged below, but not here shown, and generallyextending the whole length of a frame or bed upon which a plurality ofunits or winding-heads are supported. As the pulley H is rotated fromthe main drive-shaft its shaft h rotates the disk K, which, in turn,drives the wheel V through frictional contact therewith. By adjustingthe position of the bracket E to shift the disk K across the rim of thewheel WV the speed-ratio between the drive shaft and cam C may beregulated in the usual manner as well known in the art. Thespeed-changing device for the cam 01S operated through the movement 'ofthe winding-mandrel B away from the drive-roll D as the windingincreases in diameter to alter the speed of traverse of the thread-guidewhereby to regulate the laying of the yarn-coils in accordance with thechange in speed of rotation of the cop.

naled in the side-bearings d, d, see Figs. 1 and 2. Referringparticularly to Fig. 1, the drive-roll shaft D carries a pulley P at oneend which is belted to a pulley on the main drive-shaft of the machine,or, if preferred, the W0 shafts might be connected by gearing. Below theroll D are two parallel, horizontal rods 1", 1" extending across theinterior of the frame F and supported at their ends in the bearings f,7, see Fig. 2. Mounted on the upper rod 1" is a traverseslide L whichcarries the thread-guide G. Preferably the slide L is constructed in theform of a tubular bushing or quill to which is secured a sheetmetalmember L having the guide G made integral therewith. The member Lcomprises two spaced arms Z, Z surrounding the bushing L, as shown inFig. 5, and the connecting portion between the arms is extended upwardlyin the curved guide-member Gr. Reaching out from the side of the memberL is another arm Z bent into a hook at its end, see Fig. 2, to adapt itto inclosc the lower guide-rod r. Projecting from the bottom. of themember L is a pin or stud 0 on which is journaled a roll 0 adapted toengage with the helical groove 0 in the periphery of the cam C inaccordance with the usual arrangement. The guide-arm G is curved to,adapt it to lie close to the periphery of the drive-roll D, as shown inFig. 2, and at its top is an enlargement g bent into a vertical planeand formed with a thread-slot 9, see Fig. 5. The top of the guide G isthus arranged to 'lie close to the point of contact of the cop with thedrive-roll D and is maintained in this relation by the arm Z whichembraces the rod 1". As the cam C is rotated the engagement of itsgroove 0 with the roll 0 will cause the slide L to be reciprocated alongthe rods 1', r and the guide G will thus be traversed longitudinally ofthe axis of the winding-mandrel B.

As shown in Fig. 1, the winding-mandrel B is constructed in the form ofa tube or cylinder, generally made from wood, and having a cross-slot bat one end. The bore 6 of the mandrel or cop-tube B is adapted toreceive the ends of two opposite live spindles V, V journaled inbearings t, t at the ends of the sidearms T, T of a swinging frame U.The right-hand spindle V carries a collar or flange e on the face ofwhich is a spline or key 4) adapted to engage the cross-slot Z) in theend of the tube B to connect it rotatively therewith. The spindle V alsocarries a brakewheel or disk M through which the rotation of the tube ormandrel B is arrested in the manner and for the purpose as laterdescribed.

The frame U 1n which the mandrel-supporting spindles V, V are journaledis of substantially rectangular shape with its arms '1, T connected bythe cross-members 2 and 3. At its rearward end the frame U is pivoted ona cross-rod it held in bearings f, f on the frame F. The bearing for theleft-hand mandrel-spindle V is formed at the end of an auxiliary arm orhand-lever J pivoted at y to the side of the main arm T. A spring jserves to maintain the arm J normally in the position illustrated inFig. l to hold the spindle V in engagement with the bore of the tube B,but when it is desired to remove the mandrel the arm may be swung to oneside against the action of the spring.

Pivoted on. the rod 20 which supports the frame U atthe rear of the mainframe F is a brake-arm or lever N which also serves as the maininstrumentality for raising the winding-mandrel B away from thedriveroll D to arrest its rotation. The lever N extends along the innerside of the arm T of the frame U as shown in Fig. 1, and at its outerend is formed with an arched portion N. t the extremity of the arch N isa brake-shoe n adapted to engage with the periphery of the brake-dislr Mon the spindle V, see Figs. and 3. Straddling the sides of the portion Nof the lever N is an arm Q which is pivoted on a pin g driven throughthe lever. Pivoted on a stud 2 projecting from the side of the arm T ofthe frame U is a finger-lever Z having an arm .2 reaching out toward thefront of the machine and overlying a finger-hold extension Z on the armT. The opposite arm 4 of the lever Z is of triangular shape and ispivotally connected to the lower end of the arm Q by a stud or pin 5. Arelatively strong spring I is secured to the lower end of the lever Zand anchored at i to the extension Z on the arm T. The tendency of thespring I is to rock the lever Z in the direction opposite to thatindicated by the arrow :0, Fig. 3, to raise the frame U in relation tothe lever N to carry the brake-disk M against the shoe or, the arm Qacting as a toggle-link for this purpose, as more fully explainedhereinafter. The lever Z also serves a means for controlling thebraking-device manually and by pressing its extension z' toward thefinger-piece Z on the arm T it may be rocked to move the brakedisk Maway from the brake-shoe n in the manne and for the purpose as laterexplaincd. As shown in Fig. 8, the arm a of the lever Z is formed with asubstantially sector-like portion 6 having detent-notches 7 and 8 in itsedge adapted to be engaged by the pointed end 9 of a push-rod 10 to holdit in different positions, whereby to regulate the coaction between thebrakelever N and the frame U. The rod 10 is mounted to slide in a lug 11projecting from the side of the arm of the frame U and at its rearwardend is bent at right-angles pered groove 31 of an arcuate-shaped track 1and hooked through the end of one arm 12 of a bell-crank-lever 13. Thelever 13 1s pivoted on a stud 14: screwed into an extension 011 the topof the brake-arm N and its opposite arm 15 is pivotally connected to theend of a link or slide-bar 16 by means of the screw 17. a

The opposite end of the side-bar 16 is supported on a pin 18 driven intothe side of the cover of the main frame F and projecting through asubstantially V-shaped cam-slot 19 in the bar. The forward'end of thebar 16 is formed with a fork 20 having a slot 21 through which it isconnected to operate the yarn-releasing bail for the V thread-guide in amanner as later explained. The bar 16 also carrles a knock-0E lever 22at its outer end, preferably constructed of sheet-metal in channel formto adapt its sides to receiv a pivot-pin 23 extending through the bar.At its rearward end the bottom section of the channel is cut away at24:, see Fig. 3, to provide a cross-bar 25 which is adapted to beengaged by the teeth of a ratchet-wheel 26 attached to the hub of thecam-shaft drive-wheel WV. Two fingers or prongs 22 project upwardly fromthis end ofth lever 22 and straddle the bar 16 to guide the lever in itsmovement in relation thereto. The knock-01f lever 22 is rocked to engageits end 25 with the ratchetwheel 26 through the connection of itsforward end with the end-stop or drop-wire 7 devices of the'machine tobe later described. f Suffice it for the present to state that when itis carried into engagement with the ratchet-wheel 26 it will be movedthereby in the direction indicated by the arrow m, Fig. 3, to slide thebar 16 in the same direction. This action serves to rock the lever 13 towithdraw the detent-rod 10 from engagement with the notches in thesector 6 of the lever Z whereby to allow the latter to act in a manneras later explained.

The bell-crank-lever 13 is controlled by a spring 27 to maintain thedetent-rod 10 normally engaged with the notch 7 in the lever Z duringthe operation of the machine, asillustrated in Fig. 2. One end of thespring 27 is hooked through a hole in the arm 12 of the lever 13 and itsopposite end issimilarly secured to the end of a lever 28. The lever 28is fast on a rod 29 pivoted in bearings projecting from the under sideof the brake-lever N, see Fig. 3. The inner end of the rod 29 is bent atright-angles to its pivot portion, see Fig. 1, and extends in thecrooked arm 30. As shown in Figs. 3 and 4 the opposite sides of the arm30 are milled of? to provide a wedge-shaped crosssection which isadaptedto engage the taor quadrant 32. The quadrant 32 is secured to the mamframe of the machlne at 33, and 34, see Fig. 2, and is formed concentricwith the axis of the rod u on which the frame U and arm N are pivoted.Therefore, as these two members swing upwardly the arm 30 of the rod 29will slide freely in the groove 31 of the track 32, but on the contrary,the downward movement of the frame and lover will be resisted by thebinding action ofthe arm in the groove. This dogging effect results fromthe tendcncy of the arm 30 to rock under the action of thespring-pressed lever 28 in accordance with a familiar principle asusually employed in the winding-machine art. The lever 28 isformed witha toe-portion 35 extending forwardly from the rod 29 into positionbeneath the lower end of the lever Z. The end of the toe 35 is beveledoff at 37 to adapt it to be engaged by a latch-member 38 carried on thepivot-pin 5 of th lever Z, and also by a rounded lug 39 on the lower endof the lever, see Figs. 2 and 3. The latch 38 is preferably constructedof sheet-metal with two cars 40 straddling the end of the lower arm a ofthe lever Z and encircling the pin 5 on either side thereof. Connectingthe ears i0 is a strip-like piece 11 folded on itself at 42 and thenbent out at right-angles inthe finger 43 which bears against the side ofthe lever Z to act as a stop, see Fig. 3. The upper portion of thestrip-piece :1 extends in an angularly-bent arm 4%- which serves as acounterweight to maintain the latch normally in the position shown inFigs. 2 and 3 with its stop 43 against the lever Z. lVith th parts inthe position as shown in Fig. 3, when the arm a of the lever Z ispressed downwardly to rock its arm 4 in th direction indicated by thearrow w, the lower end of the latch 38 will wipe across the beveled endof the toe 35 of the lever 28. The latch 38 is thus caused to act as awedge to depress the toe-portion 35 of the lever 28 whereby to turn itsrod 29 to rock its dog-arm 30 downwardly. This action releases the dog30 from its binding engagement in the groove 31 of the quadrant 32, butas soon as the latch 38 rides over the bevel 37 on the toe 35 the lever28 is free to move again under the action of the spring 27. During thefirst part of the movement of the hand-lever Z the upper notch 8 comesinto engagement with the detent-rod 10, but at this juncture the latch38 will not have been carried far enough to engage the too 35 of thelever 28. Before the machine is started, however, the lever Z is presseddownwardly to bring the lower notch 7 into engagement with the detent orlocking-rod 10 to adjust the parts for operation. "When this latteroperation takes place the lever Z is moved far enough to carry the latch38 acrossthe toe 35 of the lever 28 and the dog 30 will thereby bereleased from the quadrant In this manner the dog 30 is released tobring the winding-mandrel B or the package thereon down against thesurface of the drive'roll D, and after the latch 38 swings into theposition shown in Fig. 2, the dog is freed again to allow it to bereengaged with its quadrant 32. The purpose of this arrangement isexplained more fully in connection with the method of operation of thecomplete machine.

Referring now to Figs. 1, 2 and 6, at the front of the machine is ashelf-like frame or apron A on which are mounted several sets oftension-devices Y. These latter may be of any preferred type, and ashere shown comprise three pairs of tension-plates or grids 15 arrangedin opposed relation to adapt them to press against the yarns fl/ drawingbetween their alternating bars. Extending across the frame A at the rearof the tension-devices is a rod 6, see Figs. 2 and 6, pivoted inbearings 47 and 4:8 and bent into U-shape at one end to form theextension 49, arranged parallel with its main portion 16. The free endsof the rods16 and 19 are eonnectedby an arm 50 which completes itsrectangular form and provides a loop-like frame adapted to rock in itsbearings 17 and 418. Pivotally 'lOlllltGCl on the rear rod d6 are ase'ies of breakage levers or drop-wires 51, 51, arranged in alinementwith the several tension-devices Y, see Fig. 6. Each drop-wire 51 isformed at its end with a helical coil 52 surrounding the rod -16 tosupport it pivotally thereon. From the end of the coil 52 the wireextends outwardly through a slotted opening 53 in the frame A which actsto restrain it from lateral movement in relation to its appropriatetension-device Y. At their forward ends the drop-wires 51 are bent atrightangles to form the parallel, horizontal crossbars 54:, 54, acrosswhich the yarns draw from the tension-devices Y in leading to thethread-guide G. As shown in Fig. 2 the yarns y lead outwardly from thetensiondevices to form a relative sharp bend as they draw across thebars 5 1, 55, and thence lead back over a guide-rod 56 to the slot 5] inthe thread-guide G. The guide-rod 56 extends horizontally across thefront of the frame F and is supported at one end by its bent portion 57held in a bearing 58 by the set-screw 59. In some cases the yarns maylead up from the tension-devices Y to rolls or guide-pulleys, supportedabove the ma chine, and thence back in under the guiderod 56 to thethread-guide G. This arrangement, however, being familiar to thoseskilled in the art, is not herein illustrated.

Referring still to Figs. 2 and 6, during the operation of the machinethe drop-wires 51 are supported by the yarns y in raised positionbearing against the forward crossbar &9 of the double frame std 19. Theend arm 50 of said frame is formed with an ex tension 60 which bearsagainst an adjusting screw 61 held in the front of the frame A, see Fig.2. A relatively light coiled spring 62 is hooked through a hole 63 inthe arm 50 and anchored at its lower end to a staple 6 1 held in a lug65 on the frame A. The spring 62 holds the extension 60 of the arm 50normally bearing against the adjusting-screw 61, but allows for a slightlifting of the frame-rod 16 under abnormal resistance to the draft ofthe yarn which tends to swing the drop-wires upwardly. The meanpositions of the drop-wires 51 may be regulated as required fordifferent conditions of the winding by adjusting the screw 61 to, alterthe angle of the frame some. Extending horizontallv across the frame Abeneath the drop-wires 51 is a wire-bail 66 having its ends bent atright angles to its main portion and coiled around the wire-16 at 67 and68. Projectingrearwardly from the end coil 68 is an arm 69 bentoutwardly at 70 and formed with a hook 7 lat its. extremity, see Fig. 2.Sus pended from the hook 71 is a link? 2 having its lower .end 73 hookedthrough the side of the knock-01f lever 22. It will be understood thatthe weight of any one of the drop-wires '51, upon its release by theyarn 'y, is sufficient to tilt the bail 66 downwardly to raise its arm69 and thereby lift the forward end of the knock-off lever 22. Thisaction causes the rearward end of the lever 22 to be depressed to bringitscross-bar 25 into the range of the teeth of the ratchet 26 as beforeexplained.

Extending across the top of the frame F in front of the drive-roll D isa sheet-metal cover or guard 7 5 which incloses the threadguide G andprotects it from dust and lint or contact with the operators hands. Thecover 75 is supported on a flange or ledge 76 on the tension-frame A andsecured thereto by the screws 77. At its top are sideears 78, 78 forsupporting a horizontal crossrod 7 9 on which is hinged the thread-bailor lifter 80, see Fig. 5. The bail 80 is preferably constructed in theform of a" flat, sheet-metal plate having its inner edge folded over topresent a smooth surface to the yarn. An ear 81 is turned down from itsside and into this is hooked a wire link 82, see Fig. 3. The link 82 isconnected by a turnbuckle 83 at its lower end to an ex tension 84 hookedinto the arm 85 of a lever 86. The lever 86 is pivoted on the cross-rodT, which extends across the in terior of the frame F, as previouslydescribed, and is formed with a forwardly extending arm 87. whichreaches through an opening 88 in the front of the frame E. On its arm-85. is a cylindrical stud or projection 89 which engages the slot 21 inthe forked end 20 of the slide-rod 16., When the rod 16 is slidrearwardly, through the action of the ratchet 26 on the knock-0E lever22, its cam-slot 19 engaging the pin 18 will cause its forward end to beraised slightly. This action causes its fork 20 to rock the lever 86whereby to tilt the threadbail 8O upwardly through its connection by theflange 42 engaged with its cross-slot b,see

Fig. 1, and the other spindle V is then inserted in its bore 6 at theopposite end by manipulating the lever J. The yarns y are then led upfrom their source of supply, nothere shown, but generally arrangedbelow, and inserted between the bars of the tensiongrids Y. As shown inFigs. 1 and 6 the machine is fitted with three separate tensiondevicesto adapt it for doubling or winding the yarns in multiple but a greateror less number of tensions could be used if desired. From thetension-devices Y the yarns are led up across the bars 54: and 55 of thedrop-wires 51, and thence back over the guide-rod 56 and across the .topof the thread-bail 80, see Fig. 2. It will be understood that thedrive-roll D and cam C are driven continuously from the main driveshaftof the machine which receives its motion from any suitable source ofpower, not here shown. The winding-mandrel B, however, is held out ofcontact with the driveroll D, until the winding is to be started, withthe brake-disk M bearing against the brake-shoe n as illustrated in Fig.3. This relation of the mechanism is maintained by the action of thelever Z under the influence of its spring' I when the detent-rod 10 isreleased from the notch 7 in its sector 6. The spring I tends to swingthe lever Z in the direction opposite to that indicated by the arrow 00,Fig. 3, and the arm or link Q is thus caused to hold the forward end ofthe frame U raised with the mandrel B clear of the drive-roll D. It willbe understood, of course, that the brake-arm N remains in fixed positionin relation to the drive-roll D due to the binding action of its dog 30in the groove 31 of the quadrant 32 which prevents it from movingdownwardly.

Before starting the machine to wind the cop or package the operatorplaces the fingers under the extension Z- on the framearm T and pressesdown on the end 2' of the lever Z with his thumb. This causesthe lever Zto be rocked in the direction indicated by the arrow 00, therebybringing the notch 8 in its sector 6 into alinement with the pointed end9 of the detent-rod 10. The spring 27 will then act on the lever 13 toslide the rod 10 to engage its end with the notch 8 and meanwhile theframe U will have been lowered slightly in relation to the brake-arm Nso that the disk M is clear of the brake-shoe n. The release of thespindle brake-disk M from the shoe 7;. allows the mandrel B to be turnedon its bearings so that the ends of the yarns y can be secured theretomore conveniently and wound on its surface to straighten their coursefrom the tensions. This first movement of the lever Z also brings thelatch 38 on its lower arm 4 into position adjacent the beveled end 37 ofthe toe 35 of the lever 28. Now, after the mandrel B has been rotated byhand to draw the yarns y taut, its surface is brought down into contactwith the drive-roll D to start the winding in the following describedmanner: The operator presses on the end a of the lever Z to depress itstill farther and this causes its sector 6 to be rocked to bring thelower notch 7 into position to be engaged by the detent-rod 10. Thislast movement of the lever Z will wipe the end 42 of the latch 38 acrossthe bevel 37 on the toe 35 of the lever 28 to rock the latter to releasethe dog 30. lVith the dog 30 removed from binding engagement with thesector 32 the frame U can then be lowered to carry the cop-tube Bagainst the drive-roll D. As soon as the mandrel B has thus been broughtinto driving contact with the roll D the hand-lever Z may be releasedand it will remain locked in the position shown in Fig. 2 by theengagement of the detent-rod 10 with its notch 7 With the lever Z thusheld from movement under the tension of its spring I, it will actthrough the arm Q to lock the frame U in fixed relation to thebrake-lever N, with the brake-shoe a free from the disk M, and the twomembers are thus adapted to swing upwardly on their pivot-rod u as onepart. Downward movement of the frame U and arm N, however, will beprevented by the action of the dog 30 on the fixed sector 32.

With the parts of the machine adjusted to the position as just describedand shown in Fig. 2, the drive-roll D will rotate the mandrel B throughfrictional contact of their peripheral surfaces and the cam C willreciprocate the thread-guide G back and forth longitudinally thereof.Referring to Fig. 3, it will be observed that when the windingmandrel Bis maintained away from the drive-roll to arrest its rotation, thestoppingmechanism of the machine is in such position that thethread-bail 80 will be raised on its pivot to hold the yarns 1 above andout of range of the thread-guide Gr. When, however, the lever Z isoperated to allow for placing the mandrel B in contact with thedrive-roll D the thread-bail 80 will assume its horizontal position asshown in Fig. 2, the

operation of this part of the mechanism being more fully explalnedlater. Referring now to Fig. 5, it is to be noted that the upper portiong of the thread-guide G 1S shaped somewhat like an arrow-hea d with itssides sloping outwardly from the slot g. As before stated, thethread-guide G is reciprocated continuously and hence as thewinding-mandrel B is brought down against the roll D, after thethread-bail has been depressed, the guide will ride in under the yarns yand pick them up to seat them in the slot g. In this way the gu1de G isthreaded aiitomatically as soon as the mandrel l3 starts-to rotate underthe action of the driveroll-D.

As the machine continues to operate in the manner above described, theyarn will be drive-roll D while the frame U swings on its pivot a toallow for this recession. he

bra'kedever N being lockedin relation tothe frame U is therefore causedto move with it andmeanwhile-thedog 30 acts on the quadrant 32 toprevent a return movement of the frame. Through this arrangement theframe U and the wmdmg-niandrel B are prevented from vibrating or umpmgup and'down fron'i the effect of irregularities or inequalities on thesurface of the winding, andtherefore a smoother actionof the parts 'issecured tending to improvethe character of the package. It is alsocalled to atten tion-tha-twith the parts set for the winding operation,as-shown in Flg. 2, the axis of the pin '17 which connects the slide-bar1 6 with the lever 13 is coincident with the axis of the rod u on whichthe :frame U and brakelever N pivot. Therefore, as the frame U andleverl swingupwardly with the growth of'the cop, there will be notendency todisplace the lever 13 to disturb the operative 'relation of the rod 10and bar 16.

The method of operation of the automatic stopping-mechanism of themachlne is as follows: lVhenany one of the yarns 2 becomes broken or itssupply exhausted it will allow the outer end of its-respective drop-.wire-til to fall an'dthis action will cause the ball-66, Figs. 3 and 6,to be tilted downwardly onits pivot l6. The arm 69 of the bail 66 willthereby be raised to lift the outer end of theknock-ofi' lever 2'2,whereby to depress itsrearward end and carry the crossbar 25 intoposition to be engaged by the-teeth of the ratchet 26. The ratchet 26 isrotated continuously with the cam-driving wheel 1V and during itsengagement with the end of the-lever 22 itwill act toslide the bar 16 inthe direction indicated by the arrow e,

cause it to act as a. toggle connection to raise the frame U in relationto the brake-lever N, see also Fig. 2. As before explained the arm N 1sheld from downward movement by the dog 30 and hence the fran ie U mustbe raised relatively thereto, it being also called to notice that as thelever Z is rocked to efiectthis action the latch 38 will have nooperative effect as it passes across the too 35 of the lever 28. That isto say, as the lower arm 4 of the lever Z swings to the left, asviewedin Fig. 3, the latch 38 will be free to tilt upwardly so that it willnot bear forcibly against the toe 35. Forthis reason the lever 28 willstill remain active under the effect of its spring 27 and hence the dog30 will not be released from binding engagement with the quad ant 32.

As the frame U is raisedto lift the surface of the cop away from thedrive-roll D the brake-disk M will be carried against the shoe n and themomentum ofthe cop will thereby be checked to quickly arrest itsrotation. llileanwhile, as "the slide-bar 16 is slidin the directionindicated by the arrow at, Fig. 3, to effect this ,releaseof the stoppingmeans as above explained, its forward end willgbe raised slightly asits slot 19 rides along the fixed pin 13. Throughthisaction the lever S6engaged by the forked end of the bar l6 will be rocked to raisejthe link82 connected therewith, and in this manner the thread-bail 80 is tiltedupwardly as shown in Fig. 3. As the bail 80 thus raised against theyarns y it will liftthem' out from the slot g in the thread-guide andhence the guide as it continues to re ciprocate willhave no effect totraverse the yarns. In this manner the guide is pre vented from abradingoiucuttingthe.yarns while thecop is at rest and they may also bemanipulated more conveniently in piec' ing up the ends. It shouldperhaps be eX- plainedthat the purpose of the lug 39 onthe lowerend ofthe lever Z is to provide ferreleasingthedog 30 .after the parts havebeen locked in operative relation. That is to say, if the lever .25 isfirstpressedmlown to an extentsuflicient to lock it with the detent-rod10 engaging its notch 7 before the cop is'lorought into contact with thedrive- -roll D, byrocking it to a slightly greater eX- tent its lug 39will engage'the bevel 37 on the toe 35 of the lever 28 to release thedog 30. In other words, it not absolutely till) necessary to make surethat the cop is brought against the drive-roll when the latch 38 acts onthe lever 28. This arrangement provides for a more convenient manualcontrol of the dog 30 in whatever position the parts may be set and alsoallows for the movement of the frame U even after the machine has beenstarted to operate. It is also called to attention that after theknock-off lever 22 has been operated on by the ratchet 26 it will becarried to a position with its lower web-portion above the edge of theratchet. For this reason the teeth of the ratchet will simply rideagainst the under side of the lever to hold its rearward end raised withthe cross-bar 25 out of their .pingdevices provide for a quick, positivearrest of the winding upon the breakage or exhaustion of the yarn, andif occasion requires, the stoppingmay be effected manually by simplylifting up on the end of the knock-off lever 22. The cop is brought torest almost instantly by the action of the brake-mechanism, andfurthermore the action of the thread-guide on the yarn is immediatelydiscontinued to prevent injury of the material and to provide for moreconvenient piecing up. In addition .the starting-means is so arranged asto allow for release of the brake to permit the cop to be manuallyrotated to find a broken end, or to take up the slack after the end hasbeen repaired, and in this way the operation of the whole machine isfacilitated and rendered more convenient.
